⚙️ Solids Handling (3.0" to 4.0" Solid Sphere Clearance, Specific Speed Ns 1,500-3,500)

Wastewater Pump Specific Speed & Solids Passage Calculator

Calculate hydraulic specific speed ($N_s = rac{N sqrt{Q}}{H^{0.75}}$) and solid spherical passage clearances ($3.0 ext{" to }4.0 ext{" diameter}$ / 75mm to 100mm) for municipal non-clog raw sewage pumps: balance wide vane passages against peak hydraulic efficiency, eliminate clogging from municipal wipes and debris, and pump manufacturing yields.
